W220 3.2 CDI Thermostat and Warm Up Time
Guys i want to ask about Mercedes CDI thermostat principles. I replaced thermostat but i can feel water recirculating in hose which goes to radiator, before 80 degrees. Is this thing normal ? If i try to blow in a new thermostat, it allows some air, should be bad ?
